I had to put a $get

While playing around and trying to use the iterate function with the global ^Settings on https://gettingstarted.intersystems.com/language-quickstarts/objectscript-quickstart/ I was getting an error, and using the $get function on line 20 fixed it for me. Would it not be a good practise to use the $get function on line 20 of ObjectScript.cls anyways.

Thanks.
